ZYfire Fire Hose 1-1/2-Inch ID

For a property, work area, or emergency setup that needs a 25-foot hose run, this ZYfire fire hose combines a single polyester jacket with an EPDM lining and male-to-female NST/NH aluminum couplings. Its 1-1/2-inch inside diameter and stated pressure ratings help clarify whether it fits your setup, but the connection standard matters just as much as the hose size. The listing reports UL, ULC, and FM certification, confirm that those credentials meet the requirements for your specific application before relying on them.

What to know

The hose is 25 feet long, with a 100% virgin polyester jacket and an EPDM rubber lining. The listing describes the jacket as abrasion- and flex-resistant, while the lining is presented as chemical-resistant. Aluminum couplings connect the hose at each end, with one male and one female NST/NH connection. The stated service pressure is 250 PSI, and the minimum burst pressure is 750 PSI. Those figures are not interchangeable: the burst rating is not the pressure to use as a normal operating target.

There is an important sizing detail for adapters. The coupling may be marked both 1-1/2 inches and 1-11/16 inches, the latter refers to the coupling bowl bore, not the hose’s nominal inside diameter. For adapter selection, the supplied instructions say to use a 1-1/2-inch NST adapter. Keep in mind that a matching nominal size alone does not establish compatibility with every fire protection system, so verify the connection and application requirements.

How to use it

This hose is intended to convey water through an NST/NH connection in a firefighting or emergency-water setup. Before use, identify the fittings on your equipment and match them to the hose’s male and female ends, if an adapter is needed, select it by the 1-1/2-inch NST designation rather than the 1-11/16-inch coupling measurement. For example, when laying out a short run from a compatible outlet, the 25-foot length gives you a defined reach without choosing a longer hose option. The listing also gives a temperature range of -40°F to +140°F, but it does not specify other installation or maintenance procedures.

Practical tips

Check the hose length, connection type, and required working pressure against your setup before choosing it. The product description lists 250 PSI service pressure and 750 PSI minimum burst pressure, and reports certification to UL, ULC, and FM standards. Those are useful selection details, but they do not replace checking the approval requirements for the place where the hose will be used. Compared with choosing a longer hose for more reach, this 25-foot version is the more compact run, it will not provide the same coverage if the water source is farther away. It suits you if you need this length and NST/NH fittings. Not the best choice if your equipment uses a different connection standard or requires a longer run.

Practical doubts

Is 1-11/16 inches the hose’s inside diameter? No. The listing identifies 1-1/2 inches as the hose’s nominal inside diameter and 1-11/16 inches as the coupling bowl bore measurement.

What pressure is listed for normal service? The stated service pressure is 250 PSI, 750 PSI is the minimum burst pressure.

What comes with the hose? The listing describes one 1-1/2-inch ID by 25-foot hose with male-to-female NST/NH aluminum couplings.

Buying verdict

This ZYfire hose is worth considering when a 25-foot length, 1-1/2-inch ID, and NST/NH couplings match the equipment and requirements you already have. Its material and pressure details make the listing easier to assess than a hose described only by length, but the adapter-size note is easy to overlook. Choose another length or connection type if your setup calls for more reach or a different fitting, don’t treat the burst-pressure figure as the working rating.
